  # Backslashes are needed to prevent RDoc from autolinking "Rails" to the
  # documentation of the Rails module. On the other hand, as of this
  # writing README.rdoc is displayed in the front page of the project in
  # GitHub, where backslashes are shown and look weird.
  #
  # The temporary solution is to have a README.rdoc without backslashes for
  # GitHub, and gsub it to generate the main page of the API.
  #
  # Also, relative links in GitHub have to point to blobs, whereas in the API
  # they need to point to files.
  #

  # API is no longer a generic entry point to Rails and deserves a
  # dedicated main page specifically thought as an API entry point.

# We have a webhook configured in Github that gets invoked after pushes.
# This hook triggers the following tasks:
#
#   * updates the local checkout
#   * updates Rails Contributors
#   * generates and publishes edge docs
#   * if there's a new stable tag, generates and publishes stable docs
#
# Everything is automated and you do NOT need to run this task normally.
#
# We publish a new version by tagging, and pushing a tag does not trigger
# that webhook. Stable docs would be updated by any subsequent regular
# push, but if you want that to happen right away just run this.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
